Abstract – As the current global trend towards more stringent environmental standards, technical applicability and cost-effectiveness became key factors in the selection of adsorbents for water and waste water treatment. Adsorption is by far the most versatile and widely used method for the removal of pollutants due to its high removal capacity and ease of operation at large scale. Recently, various low-cost adsorbents derived from agricultural waste, industrial by-products or natural materials, have been intensively investigated. In this respect, the eggshells from egg-breaking operations constitute significant waste disposal problems for the food industry, so the development of value-added by-products from this waste is to be welcomed. The egg processing industry is very competitive, with low profit margins due to global competition and cheap imports. Additionally, the costs associated with the egg shell disposal (mainly on landfill sites) are significant, and expected to continue increasing as landfill taxes increase. The aim of the present  is to provide an overview on the the use of chicken eggshell as adsorbent for the removal of iron from water  by the adsorption process both on simulated and real effluents containing iron onto eggshell-derived adsorbent. This was accomplished by analyzing the uptake potential for selected iron concentration at different conditions. The effects of different parameters such as pH of the solution, varying ferrous ion concentration, varying adsorbent quantities, and agitation rate and contact time on the adsorption process are to be studied. Results obtained so far shows that eggshell can remove iron from different types of aqueous systems with great efficiency.
